New Guinea Impatiens plant named ‘KLEI01028’

ABSTRACT

A new and distinct cultivar of New Guinea Impatiens plant named ‘KLEI01028’, characterized by its compact, mounded and outwardly spreading plant habit; freely branching growth habit; dark green-colored leaves; freely flowering habit with flowers positioned above or beyond the foliage; and large bright red-colored flowers.

Botanical classification/cultivar designation: Impatiens hawkeri cultivar KLEI01028.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of New Guinea Impatiens plant, botanically known as Impatiens hawkeri, and hereinafter referred to by the cultivar name KLEI01028.

The new Impatiens is a product of a planned breeding program conducted by the Inventor in Stuttgart, Germany. The objective of the breeding program is to develop new freely branching Impatiens cultivars with numerous large flowers and interesting flower and foliage colors.

The new Impatiens originated from a cross-pollination made by the Inventor during the fall of 1998 of a proprietary Impatiens hawkeri selection identified as code number A 069 not patented, as the female, or seed parent, with a proprietary Impatiens hawkeri selection identified as code number P 139, not patented, as the male, or pollen parent. The cultivar KLEI01028 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross-pollination in controlled environment in Stuttgart, Germany, in May, 1999.

Asexual reproduction of the new cultivar by terminal cuttings taken in a controlled environment in Stuttgart, Germany, since 1999, has shown that the unique features of this new Impatiens are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘KLEI01028’. These characteristics in combination distinguish ‘KLEI01028’ as a new Impatiens cultivar and distinguish it from other known Impatiens cultivars:

1. Compact, mounded and outwardly spreading plant habit.

2. Freely branching growth habit.

3. Dark green-colored leaves.

4. Freely flowering habit with flowers positioned above or beyond the foliage.

5. Large bright red-colored flowers.

Plants of the new Impatiens differ primarily from plants of the parent selections in flower color as plants of the female and male parent selections have dark red and purple-colored flowers, respectively. In addition, plants of the new Impatiens have larger flowers than plants of the female parent selection.

Plants of the new Impatiens can be compared to plants of the cultivar Delhi, disclosed in U.S. Plant Pat. No. 11,694. In side-by-side comparisons conducted in Stuttgart, Germany, plants of the new Impatiens differed from plants of the cultivar Delhi in the following characteristics:

1. Plants of the new Impatiens flowered later than plants of the cultivar Delhi.

2. Flowers of plants of the new Impatiens were bright red in color whereas flowers of plants of the cultivar Delhi were more crimson red in color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Impatiens. The photograph comprises a side perspective view of a typical flowering plant of ‘KLEI01028’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The cultivar KLEI01028 has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype. The aforementioned photograph and following observations and measurements describe plants grown in Stuttgart, Germany during the spring, under commercial practice in a glass-covered greenhouse. Plants were grown in 12-cm containers for about 12 weeks after planting rooted cuttings. During the production period, day temperatures ranged from 18 to 24° C. and night temperatures ranged from 16 to 18° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
